WARNING
FLAMMABLE FUEL
DEATH or serious injury may result if personnel fail to observe safety precautions.
Do not smoke or use open flame within 50 feet (15.24 meters) of the tank and pump unit.
Be sure proper grounding procedures have been followed prior to operating the equipment.
Do not refuel the GED pump assembly fuel can while the engine is operating; stop engine and allow to
cool before refueling.
If fuel is spilled, wash the area of spillage thoroughly with water.
After refueling operation is completed, replace the filler cap securely before removing the nozzle
bonding wire.
WARNING
Operation of this equipment presents a noise hazard to personnel in the area. The noise level exceeds
the allowable limits for unprotected personnel. Wear ear muffs or earplugs which were fitted by a
trained professional.
WARNING
All aircraft fuel must be dispensed through a filter/separator unit. It is mandatory that the performance
of filter/separators on all aircraft refueling equipment be checked every 30 days through submission of
samples taken from the effluent stream of the filter/separator.
WARNING
DEATH or SERIOUS INJURY may result if personnel fall to heed Safety Precautions for welding. Prior to
welding, read welding instructions contained in Chapter 5, on repair of the Tank Assembly.
If conditions require fuel tank repairs by welding or other methods involving heat or flame, be sure that
all fumes are purged from the tank or fill tank with water before commencing the repair. If possible, tank
should be filled with water prior to welding after being thoroughly purged of fumes. Applying heat or
flame to a fuel tank containing residue may result in a violent explosion, causing injury or death to
personnel.
Personnel engaged in purging operations will not wear wool, nylon, silk, rayon, or other similar static
electricity generating clothing. Clean cotton clothing with no metal buttons or fittings will be worn. All
contents will be removed from pockets.
The tank being purged must have a static ground during all operations. Precautions should be taken
with all tools and metal objects around the tank to ensure no spark will be made. Conduct a combustible
vapor test reading prior to purging the tank using an acceptable explosive meter.
a
TM 5-4930-230-13
Only competent personnel thoroughly instructed in the proper handling and reading of the explosive
meter will conduct vapor tests. Conduct a combustible vapor test reading immediately after purging,
Under no circumstances will repair of the tank begin until declared safe by safety personnel. Discontinue ail operations if an electrical storm is threatening or in progress. Eliminate conditions that
could cause explosions.
WARNING
Operate GED engine in a well ventilated location. Carbon monoxide is a deadly gas that is given off by a
gasoline engine. it is odorless and tasteless. The first evidence of its presence is that the operator of the
equipment will have a headache or suffer from a feeling of dizziness.
WARNING
Drycleaning solvent, P-D-680, used to clean parts is potentially dangerous to personnel and property.
Avoid repeated and prolonged skin contact. Do not use near open frame or excessive heat. Flash point
of solvent is 100 degrees F to 138 degrees F (38 degrees C to 59 degrees C).
WARNING
Do not touch metal parts with bare skin during cold weather. The skin may stick to the metal.
WARNING
Disconnect power cable from vehicle slave receptacle before replacing or repairing motor or elactrical
components. When connecting power cable be sure Remote ON-OFF Switch is in “OFF” position. L OW
voltage can cause Severe Shock or Death.
WARNING
Equipment must not be used for other than the intended purpose. Failure to heed
this warning can cause damage to equipment and/or injury or death to personnel.

personnel and can damage the equipment.
CAUTION

f. Filter/Separator. The filter/separator (figure 1-8) is a vertical, 50 gpm (189 liters per minute) unit
designed for maximum operating pressure of 75 psi (5.273 kg/sq cm). Both solids and water are removed
from the fuel through the (blending) and filtering medium of the elements inside the filter/separator. The
filter/separator consists of:
(1) Four canisters.
(2) Four filter elements.
(3) One differential pressure gage.
(4) One water sight gage.
(5) One draincock.
Any solid impurities and water in the liquid being pumped is trapped in the filter elements. The elements
hold the solid particles and the water collects and settles to the deck plate where it can be periodically
removed through the drain. Clean product builds up in the shell and is pumped to the hose reels. Refer
to figure 1-7 for flow of the pumped liquid through the filter/separator.

Section III. OPERATING UNDER USUAL CONDITIONS.
The instructions in this section are for personnel who operate the tank and pump unit. How the unit is started and
stopped in normal weather conditions is described.
Before you operate. Always keep in mind the CAUTIONS and WARNINGS.
Filling 600-Gallon (2271 Liter) Tanks.
if tank and pump unit is mounted on any vehicle other than a 5 ton vehicle,
extreme caution must be taken when filling the tanks to avoid exceeding
cross-country payload limits.
a. Be sure that suction hoses connecting tanks to the pump assembly are properly secured. Ground
pumping assembly before starting to fill the 600-gallon (2271 Liter) tanks.
b. Bonding and grounding procedures areas follows:
DEATH or serious injury may result if proper grounding procedures are not
followed prior to operating the equipment.
(1) Bonding is the process that equalizes the charge on two unlike objects such as an aircraft and a
refueling nozzle. it is done in order to prevent arcing, in the presence of flammable vapors, as the two objects
are joined.
(a) Extend the grounding cable from the ground reel assembly so the plug (if present) can be
inserted into the vehicle receptacle. Otherwise, attach one of the grounding dips to a bare metal surface of the
receiving vehicle. Attach the remaining dip to the grounding rod. Bond before the dust cap or gas tank cap is
removed to prevent a spark occurring when fuel vapor is present. Do not disconnect the bond until refueling is
complete and the gas tank cap and nozzle dust cap are replaced.
(2) Grounding of equipment is a means to provide a conductive path into the ground so a static charge
isn’t trapped on the surface of the equipment where it could discharge as a spark.
(a) Insert the grounding rod into the soil to the required depth (refer to table 2-2). Drive the rod
into the soil to reach below the permanent ground moisture level.
(b) If the top of the rod is level with the surrounding surface, scoop out an area around the top to
allow attachment of the ground dips to the rod. Attach the dip from the grounding wheel to the exposed
portion of the grounding rod. The refueler and vehicle are now grounded and the refueling process may begin.
Table 2-2. Required Depths for Ground Rods
Type of Soil
Depth of Ground Rod
Coarse ground, cohesionless sands and gravels

Inorganic clay, claying gravels, gravel-sandclay, claying sands, sandy clay, gravelly clay,
and silty clay

Silty gravel, gravel-sand-silt, silty sand, sand,
silt, peat, muck, and swamp soil
3 feet
(3) Methods of Grounding. There is no quick or easy way to test the adequacy of a ground. The testing
procedures (See FM 10-66 Appendix E) are complex and the equipment is bulky and expensive; therefore,
several levels or methods of grounding and bonding are required to meet the various operational needs of the
Army. The three methods/levels are listed in order of preference.
Change 13
2-7
TM 5-4930-230-13
(a) Method 1: equipment is grounded to a rod or rods that have measured resistance to ground
equal to or less than 10,000 ohms. Ground the refueling system or vehicle and aircraft to this tested ground
rod. Bond the nozzle to the vehide/aircraft. This method is required, unless conditions, as described below,
prevent its use. This method is the only standard of grounding acceptable, without authorization, at any fixed
airfield or refueling point. It is the safest method.
(b) Method 2: If equipment is not available to test resistance to ground, use method 2. Method 2
uses an untested ground - a grounding system based on the knowledge that damp earth will accept and drain
off an electrical charge. Use method 2 when the location, tactical situation, or type of operation makes it
impossible to test ground rods. Ground equipment to a rod or rods driven a specific depth into the ground
depending on the type of soil at the site (see table 2-2). The depth to which the rods must be driven is
determined by the normal depth of permanent ground moisture in the various types of soils. The commander of
the operating unit must authorize the use of method 2. This method is less desirable. Employ method 2 when
impossible to use method 1.
WARNING
Death or serious injury may occur if proper bonding procedures are not
followed. While using method 3, an object with a different electrical
potential (any object that is not part of the bonded system) should not
come into contact with the bonded equipment when a flammable vapor-air
mixture may be present.
(c) Method 3: When the climate, terrain, or tactical condition makes it impossible to secure a
satisfactory ground rod, requirements to ground the fuel dispenser (system or refueler) maybe waived;
however, the requirement to bond the fuel dispenser to the aircraft/vehicle may not be waived under
any circumstances. Method 3 relies on bonding alone (see paragraph 2-12b ). Bonding is made between the
aircraft/vehicle and the refueling system or refueler along with the nozzle and the aircraft/vehicle. A contact
between an unbended object and the system could produce a spark that could set off an explosion or fire.
Method 3 procedures are authorized by the commander of the unit one organizational level above the operating
unit. This is the least desirable method since it involves bonding only.
c. Open only the manhole cover fill plug of the tank being filled. Do not fill two tanks at the same time
unless operator has an assistant. If fuel is spilled, wash the area of spillage thoroughly with water.
a. General.
(1) The tank and pump unit is used to dispense automotive, aviation and burner fuel. However, only
one grade of fuel should be carried in and dispensed from the unit at a time. Since the pumping assembly is
highly adaptable, dispensing with the tank and pump unit may be done in a variety of ways to meet different
situations in the field. The following paragraphs cover some common operational procedures for the tank and
pump unit in the field (see figures 2-1 and 2-2).

Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
